sorry for the silly question, but hopefully someone can set me straight right away. i've got an old road frame that i'm thinking about converting over to a single speed first, and eventually to a fixie. but to save time/money up front, i'm thinking about just using a cheap-o rear wheel with a freehub/cassette. but then i saw some cheap flip/flop wheels and now i'm considering picking those up. but will they fit? is the spacing on the hub/axle the same for track and road frames/wheels? thanks in advance.

sometimes they're the same, most of the time they're not. you need to measure the frame spacing and then measure the hubs...
